Inclusion criteria

(Limit: 15,000 characters)
1. Patients must have a signed study informed consent prior to entering the study.
2. Patients must be between the ages of 18 and 78 years.
3. Diagnosis of active multiple myeloma (aMM) as defined by IMWG criteria.
4. At least one week (7 days) from last induction cycle of combination/multi-agent chemotherapy (e.g. KRD [carfilzomib, lenalidomide, dexamethasone] or VRD [bortezomib, lenalidomide, dexamethasone]) or from last single agent chemotherapy (e.g. lenalidomide, pomalidomide, bortezomib, dexamethasone, etc) prior to the first dose of G-CSF for mobilization.
5. Eligible for Autologous Hematopoietic stem cell transplantation according to the Investigator's discretion.
6. The subjects should be in first or second CR (including CR and SCR) or PR (including PR and VGPR).
7. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
8. Adequate organ function at screening.
9. Female subjects must be of non-childbearing potential or, if of childbearing potential, must have a negative serum pregnancy test at screening and negative serum pregnancy test within 72 hours prior to G-CSF first administration. Women of childbearing potential (WOCBP) and male subjects with WOCBP partners must agree to use highly effective contraception method during the study period and within 90 days after the last study treatment.

Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating Investigator.
